Reasons to Join the SPECapc Benchmarking Effort

SPECapc Project Committee Rules

SPECapc for Unigraphics V17 was developed by a user with 20 years of experience with the application. It is written as a series of UG Macros that run on Windows NT and Windows 2000.

New models include an engine assembly containing more than 400,000 vertices, and an intake manifold assembly containing more than 200,000 vertices. Both models are considerably larger than those used in SPECapc for Unigraphics V15.

Fifty-two (52) subtests are included within SPECapc for Unigraphics V17. Individual scores are reported for each subtest, both as elapsed time and as a normalized ratio. The reference system for computing the normalized ratio is a 700-MHz Pentium III processor with a 440BX chipset, 512-MB PC100 ECC SDRAM, 9-GB 7200-RPM SCSI-II disk, and Diamond FireGL 1 graphics card. The subtests are categorized into three groups:

• Graphics - assembly, drafting and mechanisms, 10 subtests, 50-percent weighting
• CPU-intensive - 22 subtests, 40-percent weighting
• I/O intensive - 20 subtests, 10-percent weighting
  

Each major group is assigned a score derived from the unweighted geometric mean of the normalized scores of each subtest in the group. An overall composite is derived from the weighted geometric means of the three groups.
